Describe the bug

The change in #43580 causes the kc.sh script to detach from the running console. This breaks integrations with implementations which expect the process to stay attached to the running console until the JVM process exits. For example startup scripts and probably also service management software such as systemd.

This seems like a major change in behavior but is not mentioned in the 26.4.2 release notes as far as I can tell.
